--- Comment #1 from Conrad Meyer <cem at freebsd.org> ---
Do you have a swap device or other kernel dump device configured?  If so,
please try setting debug.debugger_on_panic="0" in loader.conf and get a stack
trace / etc from crashinfo.  If not, next time 'bt' (backtrace) and a photo
would be helpful. 

You might consider renaming /boot/kernel to /boot/kernel.bad; /boot/kernel.old 
to /boot/kernel; and then 'nextboot -k kernel.bad -e debug.debugger_on_panic=0
&& reboot'.  This way you only hit the bad kernel once (if your /boot is not
ZFS) and don't need to manually use loader to find kernel.old.

There's not much to go on for now, so please provide more information and
reopen the bug.  Thanks!
